How to Change the Coolant in a 1987 Suzuki DR200
Shop parts for a 1987 Suzuki DR200 Dirt Bike.
Performing a coolant change on your 1987 Suzuki DR200 not only extends the life of your engine but keeps you running cool even during the most demanding off-road adventures. Let’s walk through a proprietary step-by-step process tailored for MotoSport customers — perfect for the 1987 DR200 and relevant for many classic Suzuki dual sports.
What You’ll Need
- Fresh, compatible motorcycle coolant (avoid silicate-based formulas for aluminum radiators)
- Drain pan for old coolant
- 8mm and 10mm sockets or wrenches
- Soft cloths or shop towels
- Distilled water (for flushing, if desired)
- Protective gloves and eyewear
Preparation: Safety First
- Make sure the engine is completely cool before beginning
- Work in a well-ventilated area, ideally with the bike on a level stand
- Dispose of old coolant responsibly according to local regulations as it’s toxic to humans and animals
Step-by-Step Coolant Change
- Remove Body Panels or Skid Plate (if equipped): The DR200’s frame may require removal of the side panel or skid plate for easier access to the water pump drain bolt. Use your 8mm or 10mm socket.
- Take Off the Radiator Cap: Slowly open the radiator cap – always do this when cold to prevent injury from pressurized steam.
- Locate and Remove the Drain Bolt: Find the coolant drain bolt at the base of the water pump and place your pan beneath. Remove the bolt and let old coolant flow out completely.
- Flush (Optional for Extra Longevity): Reinstall the drain bolt. Pour distilled water into the radiator, replace the cap, and briefly run the bike for 30 seconds (do not allow to get hot). Drain again for a cleaner system.
- Inspect Seals and Hoses: For the 1987 DR200, age may have affected the radiator hoses and seals. Check for cracks or soft spots. Replace if necessary as old hoses can fail under pressure.
- Reinstall Drain Bolt and Tighten: Always use a snug, not overtightened, fit to protect soft aluminum threads.
- Fill with Fresh Coolant: Pour the new coolant into the radiator up to the base of the filler neck. Avoid air gaps by filling slowly and gently rocking the bike side-to-side.
- Bleed Air from the System: Squeeze upper radiator hoses by hand to help trapped air escape. The DR200 does not have a bleed screw, so repeated cooling and refilling may be necessary to ensure the system is fully bled.
- Heat Cycle and Top Off: Start the engine, let it idle with the radiator cap off until the thermostat opens and coolant flows. Turn off and cool completely. Top off radiator and reservoir (if equipped).
- Reinstall Panels and Final Inspection: Check for leaks, proper coolant level, and secure all fasteners.
DR200 Owner’s Notes
- The DR200's air and oil cooling systems rely on proper coolant circulation – running low or with air pockets can cause rapid overheating.
- Aged OEM radiators and hoses on the 1987 model are notorious for fatigue. If you notice chalky build-up or bulging, replace with quality parts now to avoid trail-side breakdowns.
- Check the radiator cap seal – a worn cap can cause slow leaks and improper pressure.
- Periodically flush and refill every two years or after particularly muddy rides for best engine health.
